The Dons currently have Jesse Darko, Brennan Dickenson, Jonathan Meades, Neil Sullivan and Gary Alexander on loan.
But Ardley has a host of injury concerns ahead of Saturday's tough trip to Cheltenham and admits he may have to dip into the market again next week.
"We need to get through Saturday, see how one or two of the injuries are and then make some decisions based on that," he told the Dons' website.
"We've got one or two we are potentially looking at but it's got to be right and we are not just bringing in players for the sake of it."
